The Oologah High School class of 2017 continued a tradition of harmless pranks overnight.
This year's class of seniors left a string of underwear draped over the main entrance to the school and a sign on the building that said, "Thanks for the support but we're bustin' outta here."
The tradition of the senior class at Oologah pulling a prank like this one goes back at least several years. Last year the seniors placed thousands of Solo cups in front of the school.
The year before, the seniors covered the front entry of the school with dozens of old tires and the seniors of 2014 used hay bales and tarps to build an artificial pool in the parking lot.
The seniors usually get permission from school administrators beforehand, with the condition that they clean up the prank themselves. Some of the pranks were so involved, they became all-night gatherings as the seniors worked on their creations.
